in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...

Based on 43 Harvard CMT solutions in Yunnan region, GPS observations from 1999 to 2004 by China Crustal Movement Observatory Network, and results from SKS splitting and Pn fast wave anisotropy, we obtained the average directions of principle stress fields at different depths by average angle method. Then we further analyzed the coupling difference between geodynamic parameters in different tect...

[1] Fluid distribution in convergent margins is by most accounts closely related to tectonics. This association has been widely studied at accretionary prisms, but at half of the Earth’s convergent margins, tectonic erosion grinds down overriding plates, and here fluid distribution and its relation to tectonics remain speculative. Here we present a new conceptual model for the hydrological syst...

Many natural examples of complex joint and vein networks in layered sedimentary rocks are hydro-fractures that form by a combination of pore fluid overpressure and tectonic stresses. In this paper, a two-dimensional hybrid hydro-mechanical formulation is proposed to model the dynamic development of natural hydrofractures. The numerical scheme combines a Discrete Element Model (DEM) framework th...

Sulawesi has a complex tectonic history that is affected by major plate re-organisations during the Cenozoic resulting in an extension-dominated setting overall of convergence Indo-Australian, Pacific and Philippine Sea, Eurasian plates. It collage disparate terranes brought into juxtaposition variety processes which have occurred at very fast rates. The island subject to geohazards related ear...

Abstract The Australian continental crust preserves a rich geological history, but it is unclear to what extent this history expressed deeper within the mantle. Here an investigation of Quasi-Love waves performed detect scattering seismic surface at mantle depths (between 100–200 km) by lateral gradients in anisotropy. Across Australasia 275 new observations are presented. inferred source and a...
